Diversity Detection of Phytoplankton in Campus Lake—Taking Siyuan Lake of Shanghai Jiao Tong University for Instance
Abstract: Fresh-water algae, also called phytoplankton, are a natural and essential part of the ecosystem, and also constitute the base of the aquatic food chain. The results of this survey showed that the water body of Siyuan Lake contains 25 species of phytoplankton which belongs to Diatoms, Yellow algae, Euglenophyta, Chlorophyta, Cyanophyta and Chrysophyta. In the study, by PCR method, the mcy gene that encodes microcystin synthetase was used as a molecular marker to detect the presence of microcystis producing microcystins and potential microcystin toxicity in Siyuan Lake. The experimental results showed that the water of Siyuan Lake was slight-medium polluted. However, microcysis in the water body didn’t produce microcystins. This study provides the basis not only for detection of aquatic pollution but also for treatment of polluted Siyuan Lake.
